The Social Democrats say if they were in power they would scrap water charges in tomorrow's budget - and it would only cost €13m.
The party says it would also cut the USC by just half of one percent, reduce the property tax for mortgage holders, introduce a cap on childcare fees, and impose a tax on 'junk' food and levies on bonds and AIB pensions.
The plan would deliver 3,000 more teachers, 900 primary healthcare workers, extend parental leave by 10 weeks, give two weeks paid paternity leave, and deliver 100 megabites of broadband to schools.
Joint leader, Deputy Stephen Donnelly says their version of the budget is revenue neutral
"We don’t believe that in a growing economy the tax base should be destabilised. That is exactly what Fianna Fáil did during the bubble, and it seems their counterparts are determined to repeat that mistake tomorrow.
"By applying a small number of levies we have created the revenue space to do the following: Reduce USC; abolish domestic water charges; reduce local property tax for mortgage holders and provide a tax credit of 825 to the self employed," he said.
With 24 hours to go to the budget, the Social Democrats have become the latest to publish alternative plans.
“These services require significant investment and for that reason we have committed 100% of the €1.5billion available this year for investment in services,” said Stephen Donnelly TD, one of the Social Democrats leaders.
A cap would also be placed on childcare fees which the Social Democrats say would reduce fees by "thousands of euro a year".
The plan involves revenue raising measures to take in an additional €465m, with a focus on investment in public services.
“While it is tempting now to look at the €1.5billion and see the opportunities to try and sway people by putting an extra 5 or 10 euro back in their pocket each month, in reality, by investing in public services you can dramatically lower the cost of living thereby giving people far more back in their pocket on a daily basis than a small tax cut ever could,” Mr Donnelly said.
